IMPROVEMENT IN ADJUSTABLE lNeoT-MoLDs.

lSpecificationn torming part of Letters Patent No. 136,821, dated March. 18, 1873.

To all whom it may concern: Y Be it known that I, MAHLoN SMALLEY BRAKE, of Newark, in the county of Essex and in the State of New Jersey, have invented a new and useful Adjustable Mold for Casting Ingots; and I do vhereby declare that the fol'- lowing is a full, clear, and exactdescription ,thereof, reference being had to the accompanyin g drawing forming a part of this specilication.

Figure 1 is a perspective view, showing the mold in position for use. Fig. 2 is a )erspective view of the two parts of the mo d separated. Fig. 3 is an end elevation, toillustrate the manner of closing the mold.

A marks one half, and B the other half, of the mold. I prefer making these parts of grey` iron, because it is more porous than steel or other iron, and better allows the escape of gases, so that the ingots when cast may lie smoother and closer to the mold, and have a better surface. rlhe two parts A and B have each a rectangular angehf, of a height equal to the desired thickness of the ingot. After these parts are cast they are planed so as to coincide in surface and dimensions when vapplied together, as in Fig. 1, there being a parallel space between them equal to the height of the anges f Awhich form the edges of the mold. C marks thefb'ot-tom plate, secured by Y screws to the low'rend of part A so as to form a ange which closes the bottom of the mold'. D is the lip or mouth at the upper end of part A. E E are two Lstandards', one ot' which is cast at each end of the part A, as shown in the drawing. Projecting downward through the feet of these standards are the set-screws G, thepoints of which take into the graduated countersinks o in the top of part B. H H are the handles, of hollow form, for closing and operating the mold.

In Fig. 3 is shown the manner of putting the two parts together. The upper part B is held at an angle to part A, and the untlanged edge is slipped over the flange Vof the other part, B, until the proper countersinks come under the set-screws; as soon as this occurs the handles are griped, and the two parts come together rmly and ready for use, as shown in Fig. 1.

The set-screws serve the purpose of keeping the halves together, and of adjusting the molds for different sizes of ingots. Y

The mold being separable into halves, can

Vbe smoked over a lamp, instead of being oiled.

By this mode of smoking over alamp-iame the metal flows more freely, and is nt blistered.

That I claim is- 1' 1. A mold for casting ingots, consisting of two parts, A and B, having flanges f, substantially as and for the purposes described.

2. Part A having a bottom plate, C, and standards E E, with or without the screws G, substantially as and for the purposes set forth.

3. In combination, parts A and B, plate C, lip D, standards E E, screws G, countersinks o o o, flanges f f, and handles H H, substantially as and for the purposes set forth.

In testimony that I claim the above-described mold for casting ingots, I have hereunto signed my name this 17th day of June, 1872.
